Occasional chemical shock dosing of the pool or spa
should not damage the heater providing the water is
balanced.
Automatic chemical dosing devices and salt chlorina-
tors are usually more efficient in heater water, unless
controlled, they can lead to excessive chlorine level
which can damage your heater.
Further advice should be obtained from your pool or
spa builder, accredited pool shop, or chemical suppli-
er for the correct levels for your water.
